[Diagnostic criteria in rheumatic pelvispondylitis without radiological sacro-iliac signs. Proposals for updating].

The authors propose a limited number of changes and additions to criteria for diagnosing spondylitis without the radiological sacro-iliac signs established by Sèze and Lequesne in 1961, taking into account the evolution of the diagnostic means that have appeared since this date, especially the attempt to locate HLA 27 leucocyte antigen, now a common practice. The application of these revised criteria in 75 cases, including 41 with certain or probable spondylitis, appeared satisfactory.
